Essential details

EN 1.4439 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 1.4439 is the EN numeric designation for this material. X2CrNiMoN17-13-5 is the EN chemical designation.

It has a moderately low electrical conductivity among wrought austenitic stainless steels. In addition, it has a moderately high embodied energy and a moderately high base cost.

Typical Applications:

- Wet corrosion resistance and general service

- Plant manufacturing

- Petro chemical

- Machine engineering
